Description:  TITLE: Energy Conservation Program: Test Procedures for Direct Heating Equipment  
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy  
ACTION: Final rule  
SUMMARY: The U.S. Department of Energy ("DOE'') is amending the test procedure for direct heating 
equipment to incorporate by reference the most recent versions of the industry consen sus test 
standards previously referenced in the Federal test procedure, while maintaining the existing oil 
pressure measurement error value. DOE is also updating definitions regarding unvented heaters, 
accounting for multiple operational modes, specifying the input rate for conducting the cyclic 
condensate collection test, specifying the use of manufacturer values for gas supply pressure in 
certain circumstances, specifying the allowable range of regulator outlet pressure and specific

  gravity, providing an option to use fewer thermocouples in the thermocouple grid for models with 
small -diameter flues, clarifying instructions for calculations regarding condensate mass 
measurements, and specifying the methods to appropriately shield thermocouples from radiatio n. 
DATES: The effective date of this rule is 21 June 2022. The final rule changes will be mandatory for 
product testing starting 16 November 2022. The incorporation by reference of certain publications 
listed in the rule is approved by the Director of the Federal Register on 21 June 2022. The 
incorporation by reference of other publications listed in this rulemaking was approved by the 
Director of the Federal Register on 16 January 2013.
